Insights

Brazilian children

Area of Science:

  • Pediatrics
  • Public Health
  • Epidemiology

Background:

  • Childhood vaccination is crucial for disease prevention.
  • The COVID-19 pandemic may have disrupted routine immunization services globally.
  • Understanding vaccination trends in Brazil is vital for public health policy.

Purpose of the Study:

  • To analyze vaccination trends in Brazilian children under one year old.
  • To assess the impact of the COVID-19 pandemic on childhood immunizations in Brazil.

Main Methods:

  • Utilized monthly vaccination and birth data from Brazil's DATASUS database (2017-2020).
  • Employed interrupted time series analysis to compare pre- and post-March 2020 vaccination trends.

Main Results:

  • No significant national-level change in vaccination trends was observed before versus during the pandemic.
  • The average number of vaccinations per child was 10.6, below the scheduled 13 doses.
  • Incomplete immunization in infants is a concern.

Conclusions:

  • The COVID-19 pandemic did not significantly alter national vaccination trends in Brazil.
  • Incomplete childhood immunization remains a public health concern in Brazil.
  • Further research is needed to explore potential pandemic impacts on specific vaccines or regional disparities.

Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
